Maybe after two lights fall on your head it's time to stay in the dorm the rest of the day and definitely not cross any streets. Otherwise you might not have an opportunity for any lights to hit your head in the future.

as an electrician, i know exactly what happened. they used electrical wire to strap the lights up and twisted the wire around itself in a loop somewhere in the ceiling. but what they didn't know is that way, the lights are constantly pulling on the wire, and the insulation on the wire is slippery in that way cause its ment to slide easily through piping. so over time its like a ticking time bomb. that shit happens all the time to lights and ceilings. Workers dont really know that unless someone tells them cause its not supposed to be used. Another could be when they put the lights up to pre fit the cieling, they forget to do a final tie down, and when they try to figure out why the cieling came crashing down, they find tie wire not twisted off. Seen both happen. Bad thing about ceilings is that shit gets covered up and people dont know it until half the ceiling comes crashing down.
